IMFROVEMENT |N MACHINES FOR oRNAMENTlNc BUTTONS.

Specification forming part of Letters Patent No. 220,115. Clltd September 30, 1879; application filed June 14, 1879-.

To all lwhom t may concern:

Be it known that l, GEORGE S. BEERs, of New Milford, in the county of Litchfield and State of Connecticut, have invented certain n ew and useful Improvements in Spattering-Machines for Crnamenting Buttons and other articles; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, which form part of this specication.

Thisinvention relates to spatterin g machines or apparatus for ornamentin gbuttons and other articles, in which a rotary spattering-brush is used, -in concert with a reciprocating carriage containing` the buttons or other articles to be ornalnented by spattering.

The invention consislts in a novel construe tion of said carriage, whereby greater facilities are afforded for inserting, holding, and taking out the work preparatory to, during, and after the spatterin g process.

In the accompanyingdrawings, Figure l represents a plan -view of a spattering-machine adapted to carry out my invention; Fig. 2, a 'vertical longitudinal section of the same, and Fig. 3 a transverse section of a button or work holding carriage constructed in accordance with the invention.

A is the main frame of the machine, and B a transversely-arranged upper main drivingshaft, on which is secured a cylindrical spattering-brush, C, and which, by means of pulleys D E and belt or band b, serves to rotate a lower shaft, F. A hood, G, is used over the brush, and a drip-board below, to prevent scattering and waste of the spattering-material. 0n this lower shaft, F, is a pulley, H, which, bymmmeans of a band, c, and pulley I, serves to give motion to arot-ary feed-roller, J, that works in a trough, K,.and supplies the spatteringm ateri al contain ed in said trough to the brush C.

The brush C and the feed-roller J rotate in the same direction. The brush is revolved about five hundred revolutions per minute, and as the spattering material is worked from the feed-roller by the brush it is projected downward onto the work by centrifugalforce as reliuired, and as clearly illustrated by arrows in Upon the lower shaft, F, are also pulleys M,

which serve to give-motion by straight and cross beltsd e to loose pulleys N on a shaft, O, which loose pulleys are made to alternately gear with a sliding clutch, P, on said shaft by means of a reciprocating work-carriage, Q, driven by a spur-wheel, R, on the shaft O, in gear with a rack, f, on the under side of said carriage. This carriage is made to automatically shift the clutch P, to engage it with either pulley N, for the purpose of reversing the motion of the carriage at the ends of its stroke by means of reverse inclines h z' attached to opposite ends of the carriage and operating on a clutch-shifter, S; or any other suitable carriage-reversing mechanism may be used.

The button or work holding carriage Q is fitted to slide in ways in the main frame A, and is mainly composed of a base plate or board, 7c, which slides in the ways in the main frame, and has attached to it the rack f and inclines h t', hereinbefore described, an inde pendent and readily removable button or work holding board Z, arranged to rest on said base or on cleats secured thereto, and an upper frame or cover, m, open at its top and preferably hinged to one side of the base k, to fa cilitate the entry and removal of the buttonholding board l.

The upper open frame or cover, m, is constructed so that when closed, as shown by full lines in Figs. 2 and 3, it serves to hold and secure the button-holding board l steady and in position. Said, upper frame or cover carries 'or has its Open top provided with one or more perforated pattern sheets or strips, u, of paper or other suitable material, whereby the buttons s beneath may be spattered ina great variety of styles, or according to any desired pattern, by simply changing the perforated pattern sheets or strips n.

The operation is as follows: The trough K is charged with a preparation of white lead, and as the carriage Q is reciprocated along the frame A the rotating spatteringbrush C rei ceives the spattering-preparation from the roller J, with which it works in contact, and by reason of the high velocity at which it rotates it throws olf the said preparation and spatters it upon those part-s of the buttons s or other articles left uncovered by openings in or between the pattern sheets or strips n.

After the preparation of white lead has dried ou the buttons the latter are dipped or put into dye or color, and the unspattered parts dyed, the spattered parts being protected from the dye by the lead. After this, said buttons are tumbled in turpentine in any suitable tumbling-machiue, which dissolves oi` the lead, leavingthe formerly-spattcred parts uncolored, or of a dii'erent color by first dyeing the whole surface of the button of any desired groundcolor before passing the button through the spattering-machine, and after their passage through the spattering-machine dipping them in a dye of different color and then removing from them the white lead cast on them by the spattering-machine.

Itis found in practice that by dispensing with a check-bar, and causing the spatteringbrush to rotate at a sucieutly-high velocity to throw oli the spatterin g material by centrifugal force, the spatteriug operation is more eli'ectively performed; and besides, by dispensing with the check-bar the machine is simplied.

I claim- The combination of the base plate or board k of the carriage, the removable button or work holding board l, the movable open top cover in, constructed to hold said board in position, and one or more perforated pattern sheets or strips, n, applied to said cover, substantially as shown and described.
